Most of the mbuna are primarily herbivores or omnivores, requiring some green food in their diet. In the natural habitat, many of them feed on 'Aufwuchs' - a German word which refers to the algae covering on the rocks and the organisms within it. To meet the requirement for green foods, one option is Spirulina flake, and there are also veggie-based floating pellets available. Other green food worth trying includes cucumber or spinach chopped into small pieces, or a lettuce leaf which has been slightly crushed or briefly boiled (to soften). Other than this they can be fed a staple of cichlid pellets, normal flake and granular foods, and frozen/live foods such as brine shrimp and daphnia. As many mbuna are essentially grazers, they will benefit from regular smaller feeds, so ideally feed them twice a day. Avoid feeding only dry foods, or high protein foods such as bloodworm, tubifex and beefheart. These are not suitable for mbuna, and are often linked with the fatal "Malawi bloat" condition.
